WATCHMANS CLOCK.

SPECIFICATION forming part of Letters Patent No. 755,100, dated March 22, 1994.

Application filed May 11, 1903. Serial No. 156,662. (No model.)

To all whom it may concern.-

Be it known that I, ALoIs BEYER, a citizen of the United States, residing at Chicago, in the county-of Cook and State of Illinois, have invented certain new and useful Improvements in Watchmens Clocks, of which the following is a specification.

This invention relates to watchmens clocks of the kind described in United States Letters Patent No. 711,712, granted to me on October 21, 1902, which comprise a portable recording-clock and a number of fixed instruments or keys located at different stations for making a record on an impression-surface within the clock.

The object of the invention is to simplify and improve the manner of and means for se curing the record-impressions, as well as to provide against tampering with the recordsheet.

The invention also has in view to provide a novel station instrument carrying impression devices for operating directly upon the recordingsheet without affecting the clock mechanism or straining the parts thereof or the instrument itself.

With these and other objects in view, which will be fully and clearly pointed out hereinafter, I have illustrated one manner in which the invention may be embodied in the accompanying drawings, in which Figure 1 is a plan view of the clock with the back plate removed and shown in recording position on a station instrument. Fig. 2 is a sectional view on the line 2 2 of Fig. 1. Fig. 3 is a plan view of one portion of the periphery of the clock-casing, showing the opening therein to receive the station instrument. Fig. 4 is a sectional view on the line 4 41 of Fig. 1. Figs. & and4 are detail views. Fig. 5 is a perspective view of a station instrument. Figs. 6 and 7 are sectional views of a station instrument and showing the two positions of its movable parts. Figs. 8 and 9 are plan views of the female and male dies, respectively. I Fig. 10 illustrates a modification of the impression devices;

Like numerals of reference designate corresponding parts in the several figures, and referring thereto indicates the casing, and

16 the clock mechanism, the latter being of any suitable construction and inclosed in a suitable case. A dial-sheet 17 is mounted on a revolving shaft 18 of the clock mechanism and travels in the slotted guide 19, secured within the casing. A knife 20 is guided in a bracket 21, fastened to the casing, preferably at an angle of forty-five degrees with the pointer 22 on the slotted dial-guide. This knife is carried by a pivoted locking-plate 23, which is moved into looking or unlocking engagement with the bracket 24 on the back plate 25 of the casing by means of a disk 26, provided with a key-post 27 to receive a key. IV hen the back plate of the casing is removed, so'that a dial-sheet can be inserted in place, the knife will be projected beyond the bracket 21 in the manner shown in Fig. 4;, and the dial-sheet will rest thereon. After the dialsheet has been secured on the shaft 18 by a nut 18 or other suitable fastening means the back plate will be arranged in position with the stud in opening 61, and when pressed. to its seat the projections 28 thereon will force the paper down on the knife, which enters the slot 28 between said projections. hen the locking-plate is thrown into looking engagement with the bar 24 on the back plate, the knife will be carried back into the bracket 21 to leave the sheet free from engagement therewith, but with a slit 20 therein, from which it can be figured by reference to the relative positions of the knife and the pointer 22 at what time the dial-sheet was inserted in the clock. The dial sheet will of course be suitably marked to correspond with the usual clockdial, and the pointer enables the sheet to be properly arranged in the clock in a position to correspond with the actual time as indicated by the hands on the clock-movement dial. To remove the dial-sheet,it is necessary to release the locking-plate and throw it again into the position shown in Fig. 1, which thereby produces another slit in the sheet near its periphery and indicates the exact time at which the sheet was removed, the relative positions of the knife and pointer being considered as before. The sheet will thus bear two slits when removed from the clock, which show the exact time the sheet was put in and taken out of the clock and also provide an absolute check against tampering with the sheet, so that the watchman cannot surreptitiously replace a sheet without detection.

The station instrument comprises a frame 30, which may be suitably supported or suspended in any desired manner; but for convenience I prefer to pivotally support the frame in a bracket 31, which can be fastened at any place desired, so that when not in use the instrument may hang down in the manner shown in full lines. At night or at any other time when the instrument is to be regularly used it can be swung up to a horizontal position, as shown in dotted lines, and fastened by a pin 32, passing through openings 33 in the bracket and an opening 34 in the frame, or the instrument may be used while hanging down, as shown in full lines. I prefer also to secure the instrument by a chain 35 in addition to the bracket, so that it cannot be re moved from its station.

Each station instrument is provided with impression devices, which comprise pivoted jaws 36, carried in a slidable sleeve 37, arranged in the frame 30 and normally held outward in projected position by a spring 38. This sleeve is limited in its sliding movement by a transverse pin 39, mounted in the frame and passing through slots in the sides of the sleeve, the movement of the sleeve being suflicient, however, to permit the jaws to be brought into operative engagement with the dial-sheet 17. The jaws are normally held open by spring-plates 41, which are bent to approach each other at 42 between the pin 39 and the pivot 42 of the jaws, so that when the sleeve is forced into the frame by pressing the clock against it the spring-plates will be forced apart by the pin 39 and the jaws brought into operative engagement with the dial, Fig. 7, and an impression produced thereon by the male die 43 and its complementary female die 43. The clock is provided with an opening 44, Fig. 3, in its periphery to receive the station instrument, and a cross-bar 45 enters the slot 46 of the sleeve and engaging with the end wall thereof constitutes a stop and abearing-point at which the pressure applied to the clock is communicated to the sleeve.

1 may construct the jaws in the manner shown in Fig. 10, with their rear ends 47 extended to directly engage the pin 39 and normally held apart by a bent spring-plate 48.

Each station instrument is adapted to record at a different point radially of the dial from all other stations, and each instrument preferably records acharacter indicating its position in the circuit of all the stations, so that when the watchman completes the circuit of all the stations the impressions on the dialsheet will be consecutively arranged radially thereof from its periphery toward its center, or vice versa. Each impression on the dialsheet will indicate the particular time at which the station designated thereby was visited and the time which has elapsed between the first impression and the last impression, showing the time consumed by the watchman in making the circuit.

I have found it to be convenient to stamp each jaw carrying the female dies with all of the dies for all of the stations and then provide the male die on a strip 49, which can be adjusted in a slot 50 in the jaw to ln'ing the male die in complementary position to its female die. This enables me to readily change the characters of the stations and absolutely insures the proper positioning of the dies. The strip may be molded directly on the female dies and then cut down to lit in the slot 50 and all dies except the one to be used removed.

My improved clock is of very simple but substantial construction and its parts are not apt to be injured or get out of order in the use thereof. The impression is effected in a very simple manner by simply pressing the clock upon the station instrument, the construction of all the parts being of a complementary nature, so that the necessary pressure for producing the impression cannot be exceeded and will always be secured when the operation is properly performed. I entirely avoid all twisting and other strains on the clock which have a tendency to loosen and weaken the parts and, on the contrary, produce the impression by a direct pressure. It will also be observed that the character-impression devices are carried entirely by the station instrument and not by the clock, which enables me to make the clock in a comparatively small and compact form, if desired. I consider it of importance to locate the impressiondies so that they cannot be easily tampered with, and this is fully accomplished in my present invention, in which they are arranged approximately midway between the outer end of the jaws and their pivot.

Vithout limiting myself to the exact construction and arrangement of parts herein shown and described, what I claim, and desire to secure by Letters Patent, is

1. The combination of a watchmans clock carrying a record-sheet, and a station instrument operated by said clock and comprising movable jaws adapted to make an impression on said sheet.
